Puresys纯净系统-软件下载介绍
MKVToolNix 是一个小工具集（mkvmerge、mkvinfo、mkvextract、mkvpropedit 和 mmg），它允许您以多种方式操作 Matroska（MKV）文件。您可以使用 MKVToolNix 创建、分割、编辑、混流（封装、打包）、分离（分解、解包）、合并、提取或检查 Matroska 文件。该程序还支持其它视频格式（AVI、MPEG、MP4、Ogg/OGM、RealVideo、MPEG1/2、h264/AVC、Dirac、VC1）包括一些视频编解码器（如 VP9 视频编解码器支持 – 从 IVF/Matroska/WebM 文件读取，提取到 IVF 文件）。音频格式（AAC、FLAC、MP2、MP3、(E)AC3、DTS/DTS-HD、Vorbis、RealAudio）和大多数字幕格式（SRT、PGS/SUP、VobSub、ASS、SSA 等）。

软件特点
MKVToolNix 是一个跨平台的应用程序，可工作在 Windows（32 和 64 位版本）、Mac OS X 和 Linux。完整的软件包包含用于合并和提取流、查看信息以及编辑标题和章节的单独命令行实用程序。它们都包含在一个 Windows 版本的图形界面中。
该工具可查看、追加和分割曲目、章节和标签，并可编辑范围广泛的数据。例如，当涉及到通用轨道选项时，您可以设置轨道名称、语言、默认和强制轨道标志、标签和时间码等。此外，您还可设置宽高比、FPS、延迟、立体影像模式、裁剪、提示、压缩模式和增强功能的自定义命令行参数。外部文件可作为附件嵌入到电影中。
创建和编辑电影章节
可创建章节并定义属性，如开始和结束时间、标志、段和段版本 UID、以及章节名称、语言和国家。可配置标签文件的全局设置、创建 WebM 兼容文件、分割模式、文件链接等。值得考虑的一个重要方面是 MKVToolnix 提供了对批处理作业的支持，这意味着当执行耗时任务时您可将工作站配置为无人值守。您可检查当前的命令行并将其复制到剪贴板或保存到文件中以便在将来的项目中使用，管理队列作业，添加命令行选项，从外部文件加载章节，编辑页眉以及将项目另存为 .mka、.mkv 或 .mk3d 格式的文件。
考虑到其广泛的配置参数，MKVToolnix 应该能满足大多数用户学习、创建、编辑和生成 MKV 文件的需求。
更新日志
# Version 61.0.0 "So" 2021-08-30
## New features and enhancements
* all: IETF BCP 47/RFC 5646 language tags: implemented support for officially
registered IANA language tag extensions.
* mkvmerge: track selection: when using language tags for selecting which
tracks to keep, mkvmerge will now use component-based language tag matching
instead of comparing them verbatim. This means that only those components
(language, region etc.) the user specified will be required to exist and be
equal. For example, if a file contains three subtitle tracks with languages
`es` (generic Spanish), `es-MX` (Spanish as spoken in Mexico) and `es-ES`
(Spanish as spoken in Spain), the user can use `--stracks es` to match all
three tracks or be more specific with e.g. `--stracks es-MX` which would
only match one track. Similarly inverting the selection with e.g. `--stracks
!es` would get rid of all three tracks, not just the one for the generic
Spanish.
* MKVToolNix GUI: multiplexer: deriving track languages from file names: the
GUI can now detect full BCP 47/RFC 5646 language tags in file names. Part of
the implementation of #3173.
* MKVToolNix GUI: multiplexer: deriving track languages from file names: the
default list of boundary characters now includes `-`. Part of the
implementation of #3173.
* MKVToolNix GUI: multiplexer: the GUI now defaults to the "lower" process
priority setting for new installations in order to leave more room for other
applications, especially interactive ones. Up to and including v59 the
default was the "normal" process priority. v60 changed that to "lowest",
which turned out to be much slower on Windows for no real gain over
"lower". The setting will be auto-corrected by the GUI if the settings file
were saved last with a version between v60.0.0.0 & v60.0.0.17 & "lowest" &
it is still set to "lowest".
* HEVC dumper development tool: the tool has been renamed to `xvc_dump` and
extended to be able to dump AVC/H.264 bitstreams, too. It now also detects
the type of bitstream framing (ISO 14496-15 vs. ITU-T H.264/H.265 Annex B).
## Bug fixes
* all: IETF BCP 47/RFC 5646 language tags: fixed a corner case of wrongfully
allowing scripts/variants not listed in any of the entries in the prefix
list when the prefix list contains prefixes restricting scripts/variants and
a prefix solely with the language at the same time (example: the variant
`ekavsk` with its prefixes `sr`, `sr-Cyrl` and `sr-Latn` where
e.g. `sr-ekavsk` and `sr-Cyrl-ekavsk` should be allowed but not
`sr-Bali-ekavsk`).
* mkvmerge: HEVC/H.265: the frame type of B frames was often wrongfully
signalled as P frames instead, both with `BlockGroup` (missing second
references) and `SimpleBlock` ("discardable" flag not set) elements.
* mkvmerge: SSA/ASS packetizer: the frame numbers will now be re-calculated
when appending SSA/ASS tracks so that frame numbers of appended tracks are
always strictly higher than frame numbers of the track they're appended to.
* mkvmerge, MKVToolNix GUI's chapter editor: BCP 47/RFC 5646 language tags:
when BCP 47 language tags are used with a language code that isn't part of
ISO 639-2, the programs will now write a legacy language element set to
`und` ("undetermined") instead of not writing such an element at all or
writing one with an invalid code. Fixes #3174.
* mkvmerge, MKVToolNix GUI's chapter editor: BCP 47/RFC 5646 language tags:
the programs will ensure that the legacy and IETF language elements written
will be unique within the scope of the same "chapter display" element.
* mkvinfo, MKVToolNix GUI's info tool: in summary mode the frame type was
reported wrong for `BlockGroup` elements in which the `ReferenceBlock`
elements were located behind the `Block` element.
## Build system changes
* all: `std::codecvt_utf8` is now used instead of Boost's
`utf8_codecvt_facet`. The bundled copy the latter in `lib/boost` has
therefore been removed.
